What To Do? First time Issues.

This guy wants to have sex. I'm a virgin and he's rely experienced. We're both headed to different colleges and I don't feel pressured at all. But... he said he'd rather buy plan B than use a condom. He's getting tested before anything happens between the two of us. But, would he notice a female condom? I don't want to take any chances but I guess I don't want to ruin the mood. What should I do? Options?
